POWER BALING MACHINE.

Application filed July 20,

My invention has reference to power baling machines,,and belongs to thattype of such machines which embodies a receptacle for the material inwhich a platen is movable vertically, the movement of said platen beingimpelled by vertical screw shafts at the ends thereof. Such aconstruction is fully set forth in former application for Letters Patentof the United States filed by myself April tenth, 1925, Serial No.24,425. This class of machines is designed for handling large quantitiesof material, to be fed into the machine from above, which operationmakes it necessary that the platen be disposed of in some manner, so asnot to be an obstatie to the filling of the machine.

The chief purpose of the present invention is to provide a novel form ofplaten, and novel means forthe operation thereof, so that after it hasbeen in use in compressing the material in the receptacle it may bereturned to an upper position, and actuated so as to entirely clear thepassage for the material. This is accomplished by forming the platen intwo sections, movable from each other, and mechanism for automaticallyseparating said sections as the platen nears the upper end of itsmovement.

In the drmvings; I

Fig. 1 is a longitudinal vertical section on a substantially medial lineof a machine embodying the invention, the true proportions not beingmaintained therein, more specially as to the length of the machine.

Fig. 2 is a plan view thereof, partly in section on the broken lineindicated at 22 of Fig 1.

Fig. 3 is a cross-section on the broken line 33 of Fig. 2 with theplaten shown in a closed position.

Fig. 4 is a similar view, with the platen in open position.

Fig. 5 is a fragmentary detail, partly in section, showing the manner ofsupporting one of the platen sections.

Fig. 6 is an end View of the platen frame, with the platen closed. I

Fig. 7 is a similar view, with the platen sections separated.

Referring first to Figures 1 and 2 of the drawings, the reference number1 indicates a base, preferably formed of I-beams, upon which issupported a floor 2, provided with cross-channels 3 to receive thebale-tie wires. Upon said base is supported a frame formed ofcorner-posts 4, of channel-plate forma- 1925. Serial No. 44,684.

'whiehshafts are journaled in bearings 9 on cross-plates 10, mounted onthe base 1.

Fixed on the lower ends of the shafts 8 are volute-gear wheels 11,adapted for simultaneous operation from a common source of ower.

Vertically movable on the shafts 8 is a pair of sleeves 12, carryingtrunnions 13, upon which are rockingly mounted bearings 14, with whichare pivotally connected arms 16, by means of sleeves 15 on the ends ofsaid arms, and supported on pins projecting from said bearings.Supported by the inner ends of the arms 16 is a frame 17, having sidepieces 18, the complete frame being rectangular in form, and of asuitable size to permit the entry of material through the same into thereceptacle of the machine. Projected downwardly from the end-pieces 17are plates 19 which form supports for the ends of a pair of platensections indicated generally at 20 and 21. Each of said sections isformed of a plurality of blocks 22, spaced apart, each series of blocksbeing united at their inner ends by angle-plates 23. The spaces betweenthe blocks coincide in position with the channels 3 in the floor of thereceptacle. The end blocks of the sec tion 20 are provided on theirouter faces with angle-plates 24, the outstanding flanges of which areslidable in channels in the inner faces of the supports 19. The endblocks of the section 21 are similarly provided with angle-plates 25,the flanges of which are also slidable in channels in the faces of thesupports 19, and in spaced relation with the plates 24. (Figs. 5 and 7.)The ends of the sections are also provided with pins 27 and 28,respectively, projecting through slots 29 and 30 in the supports 19. Bythe means just described the platen sections are permitted to moveoutwardly and away from each other, leaving a space between the same ofpractically the same dimensions as those of the opening in the frame 17.The outward movement of said sections is limited by the plates 23, whichengage the side-pieces 18, as shown in Fig. 4.

In the upward movement of the platen frame the ends of the pins 27 and28 come into engagement with inclined strips l and 32, fixed to theinner faces of end-plates and 34, fixed in the main frame of themachine, and spaced apart from each other. A continued upward movementof the platen frame operates to move the pins 2'? and 28 outwardly,carrying with them the platen sections, into the positions shown inFigures 4 and 7. The strips 81 and 32 are positioned at a point higherthan the top of the receptacle so that there is no engagement the pinstherewith,'and no movement of the platen sections outwardly, until theplaten has attained a point above said receptacle. \Vith the platenparts fully separated the operation of filling the receptacle can beeasily accomplished.

In the return movement of the laten frame downwardly the pins 27 and 28engage the edges of strips 35 and 36, also attached to the end plates 83and 34 in parallel relation with the strips 31 and 32. As the downwardmovement continues the pins and platen sections are again moved inwardlyinto closed relation. The angleplates 24 and 25 are formed with inwarde:; tensions 37 and 88, which overlap, as shown in Fig. 4. By means ofsaid extensions 21 better support .is provided for the platen sectionsin their outward positions, and a more steady operation thereof secured.

Movement is imparted to the platen frame by therotation of the screwshafts 8, so as to give a simultaneous movement to the sleeves 12 in anupwardly or dow; vardiy direction, as may be desired. .ln the closedposit-ion of the platen sections, which is the position thereof when thecontents of the machine are being compressed thereby, the outer ends ofthe blocks 22 are in contact with the lower edges of the plates 18, andthe angleplates 23 are in engagement at their ends with stops 39 onth'e'fraine pieces 17. The platen is thereby held rigidly against anycompression r sistan from the contents of the receptacle beneath thesame.

The end-plates and 34 are similarly formed at opposite ends of themachine, and the lower portions thereof my be used the end-plates of thereceptacle for the material. The spaces between the end-plates formguides for the arms 16, the universal joint support of the ends-of saidarms permitting a limited amount of flexibility to the platen in itscompression action, so that it will not become jammed in position.

hat I claim, and desire to secure by Leters Patent, is;

l. A device of the class described, comprising a frame and receptacletherein, a

platen frame vertically movable in said recept-acle, and above the same,means for imparting movement to said platen frame, a platen supported insaid platen frame, formed of two sections, movable away from each otherto form an opening for the delivery of material to the machine, meansfor opening said sections at the end of the up ward movement of theplaten frame, and means for again closing the same at the beginning ofthe return movement downwardiy.
